Abstract
In a cigarette making machine, a trimming device for the formation of a continuous tobacco braid which presents alternatively consecutive points having a differentiated tobacco density, comprises a pair of coplanar and tangent counterrotating disks. Each disk is provided with at least a pair of notches and each notch presents a height, with respect to the tobacco braid, which is different from the height of the immediately consecutive notch on the same disk. A trimming paddle wheel is arranged to cooperate with the two disks so as to trim from the braid the excess of tobacco projecting between the two discs at their point of tangency. The paddle wheel presents at least two sectors in which the radial length of the paddles is reduced correspondingly to the height of the notches. The paddles of the trimming paddle wheel are arranged inclined with respect to the longitudinal rotational axis of the paddle wheel itself.
